Introduction

This is an example of a portfolio that someone might assemble to demonstrate the skills they have developed in VIS 2128. I have created this page using RMarkdown. There are fancier tools out there for creating and hosting webpages, and you are welcome to use any of those if you like. The advantage of this approach is that you can create your webpage directly from RStudio.

This example uses the downcute theme, which is available if you install the rmdformats package. The themes in the rmdformats have a table of contents that only includes level-one headings.

Other themes in the rmdformats package are material, html_clean, html_docco, readthedown, and robobook.

Your portfolio should demonstrate each of the following skills (not all of which are demonstrated in this example):

  • DONE Displaying multiple vector layers on the same map
  • DONE Calculating and displaying relationships among point and polygon layers based on distance
  • DONE Aggregating point data to a layer of polygons
  • DONE Calculating and displaying accessibility, based on travel time
  • Converting between raster layers and vector layers
  • DONE Displaying raster data on a map
  • DONE Georeferencing a raster image
  • DONE Displaying data on an interactive map

Displaying Multiple Vector Layers

Interactive Map

This interactive map demonstrates the following skills:

  • Displaying data on an interactive map

Boston Map

  • Aggregating point data to a layer of polygons

Philadelphia Map

This map demonstrates the following skills:

  • Georeferencing a raster image

Maps of San Luis Obispo

Here are two maps of San Luis Obispo, California. I might include some text here as well.

Isochrones

This map shows isochrones based on transit travel times to the nearest school. It demonstrates the following skills:

  • Displaying multiple vector layers on the same map
  • Calculating and displaying accessibility, based on travel time

Accessibility

This map shows accessibility based on a distance-decay function of the walking time to the nearest transit stop. It demonstrates the following skills:

  • Displaying multiple vector layers on the same map
  • Calculating and displaying accessibility, based on travel time
  • Displaying raster data on a map
